source_bind_attributes

Handle LOB types in Oracle. Under a certain size (4k?), you can get away with the driver assuming your input is the deprecated LONG type if you encode it as a hex string. That ain't gonna fly at larger values, where you'll discover you have to do what this does.

This method had to be overridden because we need to set ora_field to the actual column, and that isn't passed to the call (provided by Storage) to bind_attribute_by_data_type.

According to DBD::Oracle, the ora_field isn't always necessary, but adding it doesn't hurt, and will save your bacon if you're modifying a table with more than one LOB column.
